• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (((((hong hong) OR (hong kong))) or (hong jong)))) ya hua chen yan thi mong shiu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (((((hong hong) OR (hong kong))) OR (hong jong)))) ya hua chen yan thi mong shiu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (((((hong hong) OR (hong kong))) or (hong jong)))) ya hua chen yan thi mong shiu ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (((((hong hong) OR (hong kong))) or (hong jong)))) ya hua chen yan thi mong shiu ;*.
